If they were LiPo D cells they would be fine, but I've never seen LiPo in that format.
Specific power of a battery type is measured in watts/kg, and this is the key figure for achieving
flight - even a modest drone may require 100W just to hover in still air, hover flight is the least
efficient kind of flight. LiPo is the winner for specific power.
For endurance specific energy is the figure of merit - LiPo can usually achieve 5 to 20 minutes
endurance in a well engineered drone, and again is the best there is
